Subject: Cached image's files by Mime-Type
Message-ID: <47879F1D.4010809@makina-corpus.com>

Hello,

I'm trying to cache image by Mime-Type because behind varnish i've a
Zope/Plone architecture with some pictures without extension.

but this declaration in my vcl file doesn't working ::
        if (req.http.header ~ "image*" ) {
               lookup;
        }

contrary to ::
        if (req.url ~ "\.(css|js|gif|jpg|png|jpeg)$") {
                lookup;
        }

How i must interprete this ? Is my syntax bad or other ?

Thanks

You're trying to match the request headers to force a lookup, but the
request does not include a content-type header.  That's something
you'll find in the response headers.

Re,

First thanks for your response, you're right I was out ;-)

I re-read the vcl's man and i understand some details of the structure
of a vcl file so :

My first question : Vcl syntax has changed between old releases ?

My goal is to cache picture with or without extension :
So in my subroutine vcl_fetch I add :

if (resp.http.Content-Type ~ "image*") {
insert;
}

And I can't load varnish : Variable 'resp.http.Content-Type' not
accessible in method 'vcl_fetch'.
And I test with synthax seen in vcl examples (with another global
variables) and the same error appears !

Can I solve the problem ? What I miss ?

I test varnish under ubuntu os with a varnish 1.1.2 (and sometimes with
1.1.1)

That's not a valid regex (well, it is, but it doesn't do what you think)

Because there is no resp in vcl_fetch in 1.1; it's called obj.
